Title: Solenoid valve equipped with flow pare control function
Inventor: TACHIBANA YUKIMASA
IPC: F16K17/34
Filed: 1989-07-18
Abstract: PURPOSE:To reduce dimension and improve maintenance performance by installing a thick disc shaped flow rate control member which is made of elastic material and has an orifice at the center and a plunger which allows the surface of a closed loop shaped projection part to connect with and separate from the surface of the flow rate control member, surrounding the orifice. CONSTITUTION:When a coil 5 is turned OFF, an upward driving power due to magnetic force does not act onto plunger 4, and a downward force is applied by the urging of a spring 7, and the top edge surface of a projection part 4a contacts the upper surface of a flow rate washer 1 (thick disc shaped flow rate control member), and a flow passage is closed. On the contrary, when the coil 5 is turned ON, an upward driving power acts onto plunger 4 by the magnetic force, and an upward force is applied against the urging of the spring 7, and the top edge surface of the projection part 4a is separated from the upper surface of the flow rate washer 1, and the flow passage is opened. At this time, the opening area of an orifice 1a installed onto the flow rate washer 1 varies according to the flow rate, and the flow rate in the flow passage is controlled to a constant valve. The flow rate washer 1 and the solenoid valve are concentrated at one position.

Title: Production of high-purity magnesium oxide sintered compact
Inventor: YAMAMOTO SHINJI
IPC: C04B35/04
Filed: 1987-07-24
Abstract: PURPOSE:To produce a dense and high-purity MgO sintered compact at relatively low burning temperature, by adding a fluoride or chloride to a metal oxide or metal hydroxide, calcining the blend, burying MgO moldings into the resultant calcined powder and burning the composite. CONSTITUTION:A fluoride (e.g. MgF2, AlF3, etc.) or chloride (e.g. MgCl2 or AlCl3) is added to a metal oxide (e.g. MgO, Al2O3) or metal hydroxide [e.g. Mg(OH)2, Al(OH)3] and the blend is calcined at decomposition temperature or below of the above-mentioned additives. MgO moldings are buried in the resultant calcined powder and the composite is burned. The fluoride or chloride contained in calcined powder is decomposed at high temperature during burning to keep surroundings of moldings to be burned to fluorine atmosphere or chlorine atmosphere and promote sintering of the MgO moldings. Consequently, dense and high-purity MgO sintered compact can be obtained by relatively low burning temperature. Since such additives as left as impurity are not added, lowering of the purity does not occur and a special equipment or operation such as hot press is also unnecessary.

Title: High-output semiconductor laser
Inventor: KAMESHIMA YASUBUMI
IPC: H01S5/343
Filed: 1985-08-26
Abstract: PURPOSE:To improve yield, and to obtain a high output by using multilayer quantum well structure constituted of a semiconductor thin-film as an active layer, isolating a current constriction section for the active layer from a cleavage end surface through laser heating and composing the current constriction section of a region in which multilayer quantum well structure is changed into a mixed crystal. CONSTITUTION:The energy of laser beam projected from an opening section 7 is not absorbed because it is low to both band gaps of ohmic contact layer 5 and a second clad layer 4, and is absorbed by a superlattice section for an active layer 3. A mutual diffusion is generated between the layer I and layer II of the superlattice by thermal energy being absorbed, superlattice structure is broken and band gaps are reduced, heat is easy to be absorbed, and the mutual diffusion progresses. Consequently, the active layer is changed finally into a uniform mixed crystal 8 consisting of Al0.05Ga0.95As only in a laser-beam projecting section. The section turned into the mixed crystal constitutes a section corresponding to the opening section 7, a current constriction section (a current injecting section).

Abstract: PURPOSE: To quickly convert a divisor at a low cost so as to make faster division possible by converting the divisor to a certain value within a prescribed selection range before the division and converting a dividend by the same rate. CONSTITUTION: An original divisor DR is sent to a carrier selection adder 60 and a multiplexer(MX) 62, the most significant bit number of the original divisor is inspected and whether or not the conversion of the divisor is required is decided. When the conversion is not required, '1' is impressed to the control terminal of the MX 62 and the original divisor is sent to a divider. When the original divisor is not present in a desired range, the output of the MX 62 becomes the output of the adder 60 and the output of the adder 60, that is the selection range, becomes 1.5-2.0. One of DR/4 and DR/2 is added to the MX 64 depending on the size of the original divisor DR and a conversion divisor TDR is formed. The conversion the same as the conversion performed to the divisor is also performed to the dividend.
